10 speed drivetrain with 11 speed cranks

Following a bike fit, I need to change the cranks on mrs_m’s bike to something shorter. Her bike is currently running a Shimano 10 speed setup, but most of the cranks I can find are now 11 speed. Has anyone run a 10 speed drivetrain on 11 speed cranks, and was it OK, or do I need to look at a full 11 speed upgrade?

I ran 9 speed cranks on an 8 speed chain
Problem is the 11 speed chain is smaller so it will, I assume.

1. Work
2. Wear Quicker
3. Possibly be a little noisy

There were some 170mm 2×10 XT cranks in the CRC clearance – about 60 quid with a code.

It’ll be absolutely fine. No reason for extra wear or noise whatsoever.

I ran 10 speed cranks on a 9-speed setup for a while. No issues at all.

I’ve previously run 8sp cranks on a 10sp and also run 10sp cranks on an 8sp bike.

No issues for either setup.

So I assume you will have no problems.

My 10speed TT bike came with 11speed cranks as standard

11 speed slx crank and the rest of the drive train is 10 speed here, zero issues.

I am running 10speed rings with 11 speed transmission.
No problems whatsoever.
I guess the tolerances between the two are so minute.
